Mineral and Glass Filled Novolak Molding Compounds, High Temperature Epoxy is a subcategory of Epoxy. The additative is added during the manufacturing process. Its elastic modulus ranges from 2300 to 2400 MPa. Its flexural modulus ranges from 2300 to 2400 MPa. Its tensile strength ranges from 6000 to 15500 MPa at break. Its flexural strength ranges from 10000 to 21800 MPa. Its compressive strength ranges from 30000 to 48000 MPa. Its Izod Impact strength ranges from 0.4 to 0.45 J/cm. Its specific gravity ranges from 1.85 to 1.94. Its melting temperature ranges from 155 to 195 °C. Its molding pressure ranges from 0.5 to 2.5 MPa.

Epoxy is a thermoset polyadduct. Common trade names include Acme, Aerolam, Basoset, Beckopx, Conapoxy, Corlar, Cycom, DER, Desmobond, Dobeckot, Dynopon, Ecco, Epikote, Epocast, Epodite, Eprosin, Eurepox, Exatron, Grilonit, Hysol, Isochembond, Lekutherm, Lopox, Nikalet, Paraplex, Quartrex, Scotchcast, and Synthane. Epoxy possesses many useful properties: air curable, highly fillable, low shrinkage, low susceptibility to stress formation, good adhesion to almost all materials, high tensile and vibrational strength, high heat resistance, high heat deformation resistance, high chemical attack resistance, good aging properties, good electrical and dielectrical properties, odorless, tasteless, and low flammability. Epoxy is commonly used in adhesives and reactive molding compounds. Epoxy is a copolymer, which means it is formed from two different chemicals, usually referred to as the "resin" and the "hardener". Epoxy-based materials can be used for coatings, adhesives, composite materials, mold making, and electrical insulators. When working with epoxy, vinegar is an effective and safe solvent for cleaning epoxy resins from tools, brushes, skin, and most surfaces.
